will there be a new batch of U2's?

If you have problem boards in your S2 ... and still have them (not RMAd yet)
then move them to the end of the chain - to slot 10,9,...
Slot 10 is on the right, next to the PSU, and (of course) slot 1 is on the left.
Put the worst board in slot 10, next worst in slot 9 ... etc.
You can sometimes identify bad board also by the lower temperature of them.
Sometime they just hash low, but don't get any 'x's or '-'s
YMMV

No one really contacted me for RMA as far I can tell.  After about a month now, I'm still waiting for the Engineer Team's feedback, after customer service department redirects me there -- I followed the instructions like firmly press all boards down, make sure all connectors are secured, and upgraded to specific version of firmware, and the server is located in a room with AC, temp range around 70F/20C, no luck, still no full 1TH/s speed.  So my miner was running over a month under normal hashrate -- it dropped again from even 850Mh/s and even hit 500Gh/s soemtimes (to be fair, average out, it may be around 700Gh/s), and more and more "xxxxx" shows up while one fan (#4) has way higher speed than others.  I understand you guys have very busy schedule and try to be understandable and patient as much as I can.

Until this weekend -- when I check the hashrate again, it dropped to 0 -- I noticed that since fan became quiet for the first time. When I check my online hashrate, it is not really 0 Gh/s, it is about 62Mh/s (60 min average from slush's pool).  I then reboot the server via web interface, and this time, it shows 0, and no statistics at all, all sections in the miner status page is just blank with no data for each board at all. Then I have no choice but shutdown the server and go with cold reboot via power on/off button,  and this time, it even worse,  the box cannot even operate. I cannot even connect to the web interface, cannot ping the IP address (static ip) -- I tested the Ethernet line with my laptop, it is working, so no connection issue at all.  I repeated the normal troubleshoot tricks like open box and press boards, etc,  not work at all. When I power on, I can hear the fan running, and that's it, not really start hashing -- web interface not available, it seems that the Linux os messed up and not even init the ethernet.

So basically, the box is completely dead now, and I do need your help to get further troubleshoot tips or go with RMA solutions.

S3 with 28nm chips soon plz!

After purchasing 4 antminer S1's, I can say without doubt that I am completely depressed.  Only two of my units have delivered consistent trouble free results.  The other two have had to be played with  / cleaned / and restarted several times.. My worst miner, of which I am trying to have RMA'd, goes from 180 GH/s to 50-70 GH/s every night.  I have to restart it every morning and no matter what before 12 hours is out it's running at less than half speed.   I have tried:

1.) new PSU
2.) switching it to the PSU the other good units are working on
3.) cleanign all the excess thermal paste off
4.) Power cycling tens of times

Nothing seems to work.  I am leaving this review because I contacted the RMA department and asked for the RMA process to be started and that was three days ago. I have just now received a resopnse from the company, but it was only my e-mail being forwarded to the RMA department asking them to follow up with me... Now I am waiting more.... it shouldn't take 48 hours to get an RMA process started.. I am losing so much money in BTC every day that this isn't fixed.

I'm sure this company has great intentions, but the products and services they deliver fall far short of acceptable.  At this point I am under the impression I may have wasted my money buying these things.... Out of the 4 I purchased only 2 have done what they advertised they would do.  Waiting 4 days for an RMA response is unacceptable.. especially in the world of bitcoin mining where every day you're down could be thousands of dollars lost.

Hum ... I dont believe it! I still think they'll sell another batch ... why will they stop producing what they can sell??

They're discontinued, so likely never.  Although who knows, you may get lucky.  Contact Bobsag3, he alleges to have a number of S1 units in stock.
